Based on the feedbacks from customers, we changed our cable connector to Lshaped design.
Because Nikon DSLR has three connector types, we offer:
Nikon D2x, D2Hs, D2Xs, D3, D3x, D3s, D200, 300, D300s, D700, and Fujifilm S5 Pro (via accessory cable C10) (round 10 pin connector),
Nikon D90 (via accessory cable C90) (Lshaped connector),
and Nikon D3100, D5000, D5100, D7000 (via accessory cable C50) (Lshaped connector).

Here are the pictures of a Lshaped C90 cable at work with a Nikon D90 camera.
